Coleoptera of Great Smoky Mountains National Park Species Pages

Family Eucnemidae

            Tribe Macraulacini

 Dromaeolus cylindricollis (Say)

Description and Taxonomy

Length 5-8mm. The genus is an artificial collection of species that is difficult to characterize (Muona 2000). However, many eastern species, including those found in GSMNP, may be diagnosed by the following combination of characters: deep narrow lateral antennal grooves, epipleura without groove, simple claws and elongate pronotum.  In the Nearctic Region, the genus is represented by nine species subdivided into four informal species groups.  Six species are distributed the east (Muona 2000), three in GSMNP. This species may be separated from the other GSMNP species by the distinctly elongate pronotum and unicolored, yellowish body surface setae.

Life History

This eucnemid species is uncommon in GSMNP. A few specimens were collected using Malaise traps at Cades Cove and Twin Creeks ATBI plots from early June to late July at 540 and 625 m elevation.  The life history is poorly known. Reported host trees include Fagus, Pinus, Platanus and Tsuga (Muona 2000).

Distribution

Widespread, but uncommon eastern North American species, known from Montana and Quebec to Texas and Georgia (Muona 2000).

Conservation Concerns

Not under threat.
